Electricity Cost UK 2026 — Unit Rates, Standing Charges & Saving Tips

UK electricity costs 24.5p/kWh under the Ofgem price cap with a 61p daily standing charge in 2026. Average annual bill: £1,568. Fixed tariffs, smart meters, and off-peak rates can save £200-500/year.

Ofgem Price Cap: How UK Electricity Pricing Works

The Ofgem energy price cap sets the maximum unit rate and standing charge that suppliers can charge on default (variable) tariffs. Updated quarterly, the cap for Q1 2026 sets electricity at approximately 24.5p/kWh with a 61p/day standing charge. For a typical dual-fuel household using 2,700 kWh/year of electricity: annual cost is approximately £884 for electricity (£662 for units + £222 standing charge). Combined with gas, the total energy bill is around £1,568. Important: The price cap is NOT a cap on your total bill — it caps the unit rate and standing charge. If you use more energy, you pay more. The cap applies only to standard variable tariffs (SVTs). Fixed tariffs from suppliers may be above or below the cap. Recent trends: After the energy crisis peak of 34p/kWh in 2022-23, rates have settled but remain significantly above pre-crisis levels of 15-18p/kWh. Most analysts expect rates to remain in the 22-28p range through 2026-2027, with gradual declines as wholesale gas prices stabilize and renewable capacity increases.

Fixed vs Variable Tariffs: Which Saves More?

Variable (SVT) tariffs follow the Ofgem cap and change quarterly. They offer flexibility — no exit fees, switch anytime. The risk: if wholesale prices spike, your rate increases at the next cap adjustment. Fixed tariffs lock in a unit rate and standing charge for 12-24 months. In 2026, competitive fixed tariffs are available at 22-26p/kWh — potentially below or near the cap. The advantage: price certainty. You know exactly what you'll pay regardless of wholesale market movements. When to fix: If available fixed rates are below the current cap, fix immediately. If fixed rates are above the cap, stay on variable and monitor. Use comparison sites (Uswitch, MoneySuperMarket, Compare the Market) to check available tariffs weekly — the best deals appear and disappear quickly. Exit fees: Most fixed tariffs have £0-50 exit fees per fuel. Some have none. Always check before signing. If you're within 49 days of your fixed tariff ending, you can switch without exit fees under Ofgem rules. Savings potential: The best fixed tariffs save £100-300/year vs the cap rate. Some energy clubs and collective switching schemes negotiate exclusive rates.

Economy 7 and Time-of-Use Tariffs

Economy 7 provides 7 hours of cheap off-peak electricity (typically midnight-7 AM) for storage heaters and hot water. Off-peak rate: 10-15p/kWh. Peak rate: 28-35p/kWh. It's only worthwhile if 40%+ of your electricity is used during off-peak hours. Economy 10 provides 10 hours of off-peak across day and night (split into 3 windows). Less common but better for heat pump users. Agile tariffs (Octopus Agile): Half-hourly pricing based on wholesale market rates. Prices swing from -5p/kWh (you get paid to use electricity) during windy/sunny periods to 100p+ during peak demand. Average annual cost is often 10-20% below the cap for households that shift usage. Best with solar, battery, or smart home automation. Octopus Go: A dedicated EV tariff offering 7.5p/kWh between 12:30-4:30 AM. For EV owners charging overnight, this is the cheapest electricity in the UK. Annual EV charging cost on Go: approximately £150-200 for 8,000 miles. Smart meters required: All TOU tariffs need a SMETS2 smart meter. Request one free from your supplier — installation takes 30-60 minutes.

How to Save £200-500 on Your Electricity Bill

1. Switch supplier/tariff (saves £100-300): Use comparison sites monthly. The cheapest tariff changes frequently. Even saving 2p/kWh on 2,700 kWh = £54/year. Many households are on expensive SVTs when cheaper fixed deals exist. 2. Get a smart meter (saves £50-150): Real-time usage visibility alone reduces consumption by 5-10%. Plus enables TOU tariffs. Free from all suppliers. 3. LED lighting (saves £40-80): Replace all remaining halogen or CFL bulbs with LED. A household with 20 bulbs saves 60-80% on lighting costs. LEDs cost £1-5 each and last 15-25 years. 4. Heating efficiency (saves £50-200): Lower your thermostat by 1°C (saves 10% on heating). Use a smart thermostat (Hive, Nest, tado°) to schedule and zone heating. Bleed radiators annually. Draft-proof doors and windows (£10-50 DIY). 5. Appliance habits (saves £50-100): Wash clothes at 30°C instead of 40°C (saves 40% per wash). Don't over-fill the kettle — boil only what you need. Use the eco mode on dishwashers and washing machines. Turn off standby (UK average: £65/year wasted on standby). 6. Solar panels (saves £300-600): A 4kW system in the south of England generates 3,400 kWh/year, offsetting £830+ of electricity. After Smart Export Guarantee payments, total annual benefit: £900-1,100.
